Toronto and the GTA had its first snowfall affected commute. Hopefully everyone relearned how to drive in winter weather.

Now, here comes those cold, cold temperatures that The Weather Network says are "more typical of mid to late December."


And after enduring that slow commute (or TTC delay!) the forecast calls for a second "much stronger blast" that will hit the traditional snowbelt areas later Thursday, bringing with it "dangerous lake-effect snow and significant totals that will persist through to the weekend.

All in all, the forecasters say, November is shaping up to be a "tumultuous" time.

And while the snow is gone now, the falling temperatures combined with the wet roads could lead to some very icy conditions this afternoon and evening.

"Even for the fully prepared, the first measurable snowfall of the season was still a big shock to the system across southern Ontario," The Weather Network reported.

Driving on Friday in the traditional snowbelt areas could be tricky with heavy snow approaching and delivering in the traditional snowbelts  up to 20-40 cm of snow through Friday, with squalls persisting until Saturday morning.

"We've had dustings of snow, but this by far, is posing a serious threat if you're travelling in the region," says meteorologist Tyler Hamilton. "Even though things go seemingly calm through the early afternoon on Thursday, what's lurking over the shores of Lake Huron starts to drift towards Grand Bend, Strathroy and London late Thursday evening."

Friday and Saturday's daytime highs will just barely touch or rise above freezing, though it will feel much colder due to wind chill.

"Narrow bands of lake-effect snow will also continue southeast of Lake Huron and Georgian Bay and could extend into parts of the GTA at times with heavier flurries," meteorologist Dr. Doug Gillham says.

Sunday warms a bit with some rain and then it's back to those late December-like temperatures.
